ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 295,059, dated Marclrll, 1884.

` Application filed November 3, 1853. (No model.)

.To all whom t may concernr Be it known that I, EDWIN Ii. SH'UTE, of Ansonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in Electric Gas-Lighters; and I do hereby -declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, t0 be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a side view, Fig. 2, a top or plan View; 3, a side view at right angles to Fi 1;'Eig. 4, the armatures in connection with the gas-cock; Eig. 5, a modification; Eig. 3, the locking device as engaging the cock in the cut-off position.

This invention relates to an improvement in that class of automatic gas-lighters in which an electro-magnet is connected at\one end with the wire through which the current of electricity is passed, and at the other with a circuit-breaker at the gas-burn er, and arranged so that the current oi" electricity is passed to the circuit-breaker through said magnet, attracting an armature in lconnection with the gas-cock, whereby the gas is automatically turned on and lighted by thc spark produced at the. tip of the burner `from'said magnet in the circuit, and in which, in some cases, a second magnet is arranged, the armature oi' which is also in connection with the gas-cock, and so that a current of electricity through said magnet will attract its armature and cut off the gas. i

Before referring to my improvement I will brieiiy describe the general construction.

A, Fig. 3,1epresents the gasburner, attached to the gas-fixture by its socket B, in the usual manner of attaching gasburners. At one side of the burner is a magnet, C, over which an armature, D, is hung upon a pivot, a, and so as to swing up and down from and toward the. polesv of the magnet. From the pivot-point of the armature D an arm, E, extends into connection with the gas-cock E, as seen in Eig. 4t, and so that by turning the armature from the position seen in Fig. 3 to that seen in Fig. 4 the plug of the cock will be turned to open the gasway, and the armature raised will turn the arm E in the opposite direction and cut This consists of two platinum or other ing through a socket, I, on thebracket G, and l extends below the bracket, and is there provided with a spring, K, the action of which is to hold the point d down upon the point I), as Seen in Fig. l. The armaturedever extends beyond its pivot, and so as to stand beneath the cxtreme lower end, f, of the rod I, and so that when the armature D is drawn down, as seen in broken lines, Eig. 3, the extension on the opposite side of the pivot will strike the lower end, f, ofthe rod H and raise that rod before the armature comes into contact with the core ofthe magnet to close the circuit. This movement of the armature and rod II raises the point d from the point b, Aforming an arc, and producing a spark to light the gas, which has been turned on by the movement of the armature, as before described. Immediately on the opening of the circuit, and which is done so soon as the gas is lighted, the spring K forces the rod H downwardand brings thc points Z) (l again into contact. The action of this spring, through the rod upon the armature, necessarily raises lthe armature, and consequently turns the plug ol the cock to the extent of such movement. The plug must necessarily work with great freedom. The armature being free, it frequently occurs that on the breaking of the circuit the movement of the armature, un der the action ofthe spring K, will be greater than desirable, and hence will cut oit a considerable portion of the gas. Again, standing free, as it necessarily must, it is liable to movement under any jar or shock which may accidentally be brought to the burner. Such jar or shock is frequentlysuilicient to entirely cut off the gas. Particularly is this the case where, as represented in the drawings, a second magnet, L, is arranged upon the opposite side to the magnet C, the armature-lever eX- tended across and carrying at its opposite end IOO the armature )I of the magnet L, the armaturc M. substantially counterbalancing the armature D. The magnet L is employed to extinguish the gas. This is done byclosing the circuit and bringing the armature M upon the pole of the magnet, as seen in Fic. 3, the circuit being openedso soon as the gas is extin- `guished, it being understood that this device is Worked on an open circuit. The same dit iieulty which I have described as existing in the liability oll the gas being cut oit' exists in the liability ofthe gascock to be opened when once it has been extinguished.

The object o'l my invention is to overcome these difficulties; and it consists in a locking device in connection with the armature-lever, whereby when the gas-cock is opened the armature Will be locked in that position, and released from such lock when the circuit is closed forthe purpose ol' cutting oil" the gas, and also in a like locking mechanism in connection with the armature, so as to lock the armature 'in the cutoi't' position, such lock being opened by the closing ol' the circuit, which opens the gas-cock, and as more l'ully hereinafter described. On the axis upon which the armatures turn I arrange a disk, N, in the periphery of which is a notch, 7L, or it maybe simply an arm extending from the axis, in the end ot' which the notch 7e. is formed.

t' is a dog hung upon a spring, I, the'nose of the dog arranged to engage the notch 7i when the armature D is drawn down to open the supply ot gas. Upon this dog is an armature, l, and beneath it is a magnet, lli, the core m in such relative position to the armature Z that when the circuit through the magnet It is closed it will attract the armature and draw the dog `from its engagement with the notch h. This magnet It is in connection with the magnet L, so that when the circuit through the magnet L is closed to attract the armature )I the magnet It will attract its arn'n'iture and dranv the dog/Ll from the notch 7l.

Suppose the parts to be in the position oi" gas cut oit, as seen in lig. 3, the circuits open. To light the gas, the circuit through the inagnet C is closed, which causes its armature D, as before described, to let on the gas and pro duce the spark. As the armature I) approaches its magnet, the nose of the dog lalls into the notch 71, and locks the armature in that position, so that accidental turning of the gas-cock is impossible. AWhen the gas is to be extinguished, the circuit through the magnets L and it is closed, the iirst action oi" such closing being that the magnet It will attract its armature 't and draw the dog t'. from its loekin g engagement with the notch 7L; then the armature, being lree to turn, is brought into contact with the magnet L, and the gas cnt oft'. To lock the armature or armaturelever in its cut-oft' condition, a like disk, N', is arranged upon the opposite end of the axis of the armature, and a like magnet, It', arranged in connection with the circuit through the magnet C. A like dog, if, is arranged to engage a like notch, 71.', (see Fig. 3,) and so that when the circuit through the magnet C is closed to let on the supply ol" gas the dog will be iirst drawn from its engagement with. the notch h, thus leaving the armature D free to be drawn to its magnet and open the supA ply. This locking mechanism for the armatures may be applied to other and similar gas` lighting apparatus. I therefore do not wish to be understood as limiting this locking apparatus to the precise arrangement of magnets, armatures, and circuit-breaker shown.

It will be readily seen that the dog may be applied to the gas-cock directly, and produce the same result, say, i seen in Fig. Therefore, while I prefer to apply this locking device to the axis ofthe armatures, l'. do l not Wish to be understood as limiting my inrention to that particular arrangement.

I claim-- l. In an electric gas-lighting apparatus, the combination ot' the gas cock and burner, two magnets-one in connection with the circuit for opening the supply ot' gas, the other in connection with the circuitfor cutting oit the supply of gaswthe armatures ot' said magnets in connection with the gascock, the magnet R in connection with the magnet i'or cutting ott' the supply of gas, and a spring-dog arranged to automatically lock the gas-cock in its open position, said dog attached to or made a part of the armature of said magnet It, and whereby said dog will be released from its engagement upon the closing ot the circuit for cutting ott' the gas, substantially as described.
